Glad to hear you have it installed. Normally I find the first 5000km or so the exhaust is quite but after that get louder.

 

Just heard a jk without the muffler boy does it sound bad. I thought it was a Honda civic

 

Planning on changing mine as well soon. Most likely gonna buy a magnaflow cylinder shaped exhaust (universal) and get a muffler shop to add 2.5" tubing to make my own "off road" exhaust. Gonna dump the pipe right before the rear axle.
Will try to leave the stock resonator so it's not too loud. Cost, $100 for the exhaust + maybe another $150 for the custom tubing

 

Let me know how that works out
